GAS-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 333,584, dated January 5, 1886,

Application filed October 3, 1885. Serial No. 178,946.

To all whom it may concern.-

Be it known that I, MYRON J. AMIOK, of Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Automatic Gas- Regulators, of which the following is a specification, reference being bad to the accompanying drawings, which illustrate my improvements.

My invention relates to that class of regulators used to regulate the pressure and flow of illuminating-gas through the supply-pipes of buildings.

My improvements consist in certain combinations of parts, hereinafter described and claimed, by which I obtain a satisfactory action of the valve, prevent vibration, and secure a liquid seal in small space, together with simplicity, durability, compactness, and economy of construction.

In the accompanying drawings, Figure 1 is a vertical central section throughmy improved gas-regulator. Fig. 2 is a vertical central section through the outside case. Fig. 3 is a vertical central section through the reservoir for containing the liquid seal. Fig. 4 is a vertical central section through the gas-drum, showing the tubular guide secured within it; and Fig. 5 is a vertical central section of the double tubular guide.

All the parts illustrated in Figs. 2 to 5, inclusive, are shown detached, while Fig. 1 shows them organized together.

Referring to the letters upon the drawings, in aid of a description in detail of my improvements, A indicates the outside hemispherical case, which may be cast integral with the inlet B, an outlet, O,and with the flange D around its margin at the top. The inlet and out let projections B and O, with openings through them, may afterward be screw-threaded, as shown, for the attachment of gas-pipes.

E indicates the circular inner casting forming the annular receptacle for the liquid seal, and provided with a flange, F, around its upper margin,adapted to fit over and be secured upon the-flange D of the case, as shown in Fig. 1. The double tubular guide G is secured to the inner casting, E, as shown in Fig. 1.

H indicates the gasdrum, preferably made of sheet metal, as usual, provided with the (No model.)

that the great body of the liquid is outside of the drum, and only a small surface of the liquid is exposed to pressure of gas within the drum. This arrangement produces a better seal with a given volume and depth of liquid.

M indicates the cap, preferably having a rounded contour, as shown, and having a marginal flange, N, to seat it, as shown in Fig. 1. This cap may also be of cast metal, and be secured in place by bolts or rivets, or in any other usual manner.

0 indicates a short bulbous section of pipe, in which is the valve P, connected by the rod Q, to the top of the gas-drum. The lower end of the rod is preferably screw-threaded and connected to the valve in that Way, so that the valve may readily be adjusted on the rod to any desired position. The valve is also preferably rounded on its exterior, as shown, by which a more equable pressure of the gas for the purpose of seating it is secured, as in case of a ball-valve.

R indicates a pin on top of the gasdrum and at one side of the center, the purpose of which is to hold one or more suitable weights, R, to prevent vibration of the drum, so that its movements will always be up and down steadily in the same plane, which gives better results, the action of the regulator being more uniform and certain. This plan is much superior to that in which ordinary guides are used, because they cause friction and detract from the delicacy and accuracy of the regulator.

S indicates a guide for the val.ve-rod, and there might be two of these, if desired. The regulator, it will be seen, has the form, approximately, of a hemisphere, which is convenient to make and is shapely in appearance.

The operation is as usual in this class of gas regulators, the gas entering and passing out as indicated by the arrows, and the gas-drum responding to pressure and operating the valve properly to cause the flow of gas to be generally uniform.

IOO

It will be observed that I use the ordinary elements of this class of gas-regulators; but, as I claim, of improved construction and organization together, and as I will now specifically point out and sum up in my claims.

\Vhat I claim as new, and desire to secure the flanged hemispherical case A, the flanged inner circular casting, E, the double tubular I 5 guide G, the gas-drum, the guide K, carried by the gas-drum,and the weight B, applied to one side of the drum, substantially as set forth.

In testimony whereof I have hereunto sub- 20 scribed my name.

MYRON J. AMIOK.
